Computer Organization and Architecture - 11e
by William Stallings
This top-level view of structure and function is important because of its explanatory power in understanding the nature of a computer. Equally important is its use to understand the increasingly complex issues of performance evaluation. A grasp of the top-level structure and function offers insight into system bottlenecks, alternate pathways, the magnitude of system failures if a component fails, and the ease of adding performance enhancements. In many cases, requirements for greater system power and fail-safe capabilities are being met by changing the design rather than merely increasing the speed and reliability of individual components.⏎ ⏎ This chapter focuses on the basic structures used for computer component interconnection. As background, the chapter begins with a brief examination of the basic components and their interface requirements. Then a functional overview is provided. We are then prepared to examine the use of buses to interconnect system components.🏁
